Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, and in particular to a handheld vacuum cleaner with a trigger switch assembly. Background Technology

[0002] A handheld vacuum cleaner with a trigger switch assembly is a portable cleaning device. Using the trigger switch as its main control component, it provides users with a convenient and flexible operating method. When the user presses the trigger switch, the circuit is activated, the battery pack powers the motor, and the motor drives the fan impeller to rotate at high speed. This creates negative pressure within the suction pipe, generating powerful suction that draws dust and debris into the vacuum cleaner body. The sucked-in air passes through a filtration system, trapping dust and impurities in the filter screen. The purified air is then expelled from the vacuum cleaner, preventing secondary pollution.

[0003] In scenarios requiring prolonged and continuous cleaning, such as cleaning large floors, pressing the self-locking button keeps the trigger locked, allowing the vacuum cleaner to run continuously. Users don't need to constantly hold down the trigger, giving them more freedom of hand control and improving cleaning efficiency. For handheld vacuum cleaners with multiple cleaning modes, the self-locking button can be associated with different modes. For example, a short press activates the normal suction mode, while pressing and locking the trigger enters the powerful suction mode. This allows users to quickly switch modes according to their cleaning needs without frequently searching for the mode switch button during cleaning. Users can flexibly choose whether to use the self-locking function based on their actual cleaning requirements. When cleaning areas where the vacuum cleaner only needs to be used briefly, not using the self-locking button and pressing the trigger as needed avoids unnecessary prolonged operation, saving power, extending battery life, reducing charging frequency, and improving ease of use.

[0004] During prolonged cleaning sessions, users need to hold down the trigger to keep the vacuum cleaner running. This keeps hand muscles in a state of tension for extended periods, easily leading to hand fatigue, soreness, and even affecting normal use and cleaning efficiency. Because of the need to continuously press the trigger, users become distracted while operating the vacuum cleaner, making it difficult to concentrate fully on the cleaning action, thus affecting the thoroughness and efficiency of the cleaning. Furthermore, prolonged trigger pressing can cause finger numbness or tremors, further affecting the precision of control over the vacuum cleaner and making it difficult to thoroughly clean narrow spaces or corners. Therefore, a handheld vacuum cleaner with a trigger switch assembly is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a handheld vacuum cleaner with a trigger switch assembly, aiming to improve the problems of difficulty in accurately controlling suction power, hand fatigue, and inconvenience in use in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A handheld vacuum cleaner with a trigger switch assembly includes a housing 1, characterized in that: a housing 2 is fixedly connected to the left end of the housing 1, a transparent shell is fitted onto the left end of the housing 2, a detachable mechanism is fixedly connected to the outer side of the housing 2, and a self-locking mechanism is provided inside the housing 1.

For vacuum cleaners requiring regular filter replacement, the quick-disassembly design simplifies the filter replacement process. Users can complete the replacement without complicated tools or spending excessive time, ensuring the filter structure is always in good working order, extending the overall lifespan of the vacuum cleaner. Timely disassembly and cleaning of the filter structure effectively prevents filter clogging caused by excessive dust accumulation. With an unobstructed filter, air can pass through smoothly, maintaining a stable and powerful suction, thereby improving cleaning efficiency and ensuring good cleaning results every time it is used.

The fixing rod 308 slides into the groove opened in the transparent shell 5 through the operation of the components, so as to fix it.

[0041] Working principle: When the user presses button 2062, the force is transmitted through connecting plate 2061 to transmission rod 206, causing it to slide down along the inner wall of transmission ring 1 203. The teeth at the bottom of transmission rod 206 mesh with the teeth at the top of transmission ring 205, driving transmission ring 205 to rotate counterclockwise and causing connecting rod 1 204 to compress spring 1 202 downward. Spring 1 202 stores elastic potential energy, causing the outer wall of button 2062 to contact the vacuum cleaner switch, closing it and activating the circuit to start the motor. When the user presses button 2062 again, spring 1 202 releases its elastic potential energy, pushing connecting rod 1 204 upward to reset, causing transmission ring 2 205 to rotate clockwise and move upward. Transmission ring 2 205 drives transmission rod 206 to slide upward through tooth meshing, causing button 2062 to return to its initial position. Button 2062 separates from the vacuum cleaner switch, and the motor stops working.

[0042] When the user presses the pressing rod 302 inside the square box 301 on the outer wall of the outer casing 2 4, the pressing rod 302 drives the fixing plate 1 303 to move to the left. The force is transmitted to the fixing block 305 through the connecting rod 2 304. The fixing block 305 drives the connecting rod 307 and the fixing rod 308 to slide downward in the square box 301. At the same time, the spring 2 309 at the bottom of the fixing plate 2 306 is compressed, causing the fixing rod 308 to exit from the slot or hole of the detachable part of the vacuum cleaner, releasing the locked state and making it convenient for the user to disassemble the part. When the pressing rod 302 is released, the compressed spring 2 309 releases its elastic potential energy, pushing the fixing rod 308, the connecting rod 307 and the fixing block 305 to return to the starting position. The fixing rod 308 is reinserted into the slot or hole. The limiting of the connecting rod 307 by the fixing plate 2 306 ensures accurate reset and achieves a firm lock on the detachable part.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
